Abstract

PURPOSE:To sharply reduce the occurrence of erroneous contact with a heat resisting glass and to prevent the occurrence of a burn by a method wherein residual heat display parts responding to the number of hot plate part are mounted in the vicinity of the respective hot plate parts to discriminate the presence of a residual heat. CONSTITUTION:Heat resisting glass 2 is mounted to an upper surface opening part 3 of a device body 1, and three hot plate parts 5 each having a heat source 4, e.g. a halogen lamp, are mounted in the device body 1. A residual heat display part 6 located in the vicinity of the hot plate 5 is provided, in order, from below with a light emitting part 7, e.g. a mini lamp, the other glass plate 8 on which a mark to arouse an attention for no contact with the glass plate is put, and a heat resisting glass 2. The light emitting part 7 and the other glass plate 8 are formed with a lamp house 9. When the temperature of the hot plate 5 is high, through turning ON snd OFF of the light emitting part 7, e.g. a mini lamp, mounted to the residual heat display part 6, flickering is effected, and a clear mark to arouse an attention for no contact with the heat resisting glass is put on a display zone 10 of the heat resisting glass 2. In this case, since the residual heat display parts 6 are mounted in a number responding to the number of hot plates 5, it is rapidly detected that a heat remains at which hot plate part 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking appliance equipped with a residual heat display device within the main body.

2. Description of the Related Art Conventionally, this type of cooker is shown in FIGS.
As shown in (C), a heat-resistant glass 2 is attached to the upper opening 3 of the appliance body 1, and a plurality of stove parts 5 each having a heat source 4 such as a halogen lamp are provided inside the appliance body 1. Further, residual heat display sections 6 having light emitting sections 7 such as LED lamps concentrated in the front center of the appliance body 1 are provided in accordance with the number of stove sections 5 (see Fig. 4). Alternatively, only one representative structure can be installed in front of the center of the device body 1 (see Figure 4).
C)). The residual heat display section 6 indicates whether the stove section 5 is high or low temperature, that is, whether there is residual heat in the heat-resistant glass 2.
The presence of residual heat in the heat-resistant glass is determined by turning on and off (turning on or off) a light-emitting unit 7 such as an LED lamp provided in the display zone 10 to blink the display zone 10. Problems to be Solved by the Invention However, in this configuration, the residual heat display section 6 is located at a distance from the stove section 5, and if you don't look closely, you can see that the stove section 5 is visible.
It is difficult to determine whether there is residual heat or not. Another problem was that it was difficult to determine which of the plurality of stove sections 5 had residual heat unless it was carefully confirmed. As a result, a person using the cooker may touch the heat-resistant glass 2 and get burnt because it is difficult to understand, and a person who does not use the cooker often may not notice and touch the heat-resistant glass 2. Touching it could cause burns.

Furthermore, as another method, there is a method of enlarging the display zone 10 and causing the display zone 10 to blink by turning on and off the light emitting part 7 so that it is easy to check whether there is residual heat, but in this case, When you use another stove (meaning that the other stove is energized) in addition to the stove that has residual heat (the display zone is flashing), you will see the blinking display zone 10, which has been enlarged and made easier to understand. This resulted in inconveniences such as people getting irritated and having to cook the food themselves. Therefore, the first object of the present invention is to provide residual heat display sections 6 near the stove sections 5 in accordance with the number of stove sections 5 to facilitate determination of the presence or absence of residual heat.

The second purpose is to prevent people from touching the heat-resistant glass 2 with residual heat by flashing the mark that warns of burns due to residual heat through the heat-resistant glass 2 by turning on and off the light emitting unit 7. It is. The third purpose is that when there is residual heat in one of the multiple stove sections and the display zone is blinking, when the power is turned on to cook on another stove section, the cycle of the blinking becomes gentler and the display zone becomes less noticeable. The flashing cycle has been devised to enable cooking.

Means for Solving the Problems In order to solve the above problems, in order to control the residual heat display of the cooker of the present invention, a plurality of stove parts are installed in the main body of the cooker having a heat-resistant glass attached to the upper opening, and a warning alarm is provided. At the bottom of the other glass plate on which the mark is printed, there is a residual heat display part constructed from a lamp house equipped with a light emitting part, and the light emitting part changes depending on whether the stove part is energized or de-energized. The on/off blinking cycle is controlled to be fast or slow.

Effect The cooker of the present invention has the above-mentioned configuration, so that when the temperature of the stove part 5 is high, the light emitting part 7 such as a mini lamp provided in the residual heat display part 6 flashes on and off to remind people not to touch it. A mark is clearly displayed in the display zone 10 of the heat-resistant glass 2. At this time, since the residual heat display sections 6 are provided according to the number of stove sections 5, it can be quickly determined which stove section 5 has residual heat. The temperature of the stove part 5 decreases over time,
When the temperature falls below a predetermined temperature, a thermometer (not shown) installed in the stove part 5 detects the temperature, turns off the light emitting part 7 such as a mini lamp, and the mark to remind residents not to touch it is removed. be done.

Next, when one of the multiple stoves has residual heat and the warning mark is blinking in small increments due to the on/off of the light emitting section, when you turn on the power to the other stove and cook,
Since it is a nuisance, the blinking cycle is made slower.

Then, when you finish cooking and turn off the power to the stove, if there is still residual heat on the other stove, the flashing cycle will return to the original and blink in increments.Furthermore, the display zone of the stove that has finished cooking will change to a new one. It will blink in a smiling cycle.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings FIGS. I to 3. Note that the same members as in FIG. 4 are given the same reference numerals.

A heat-resistant glass 2 is attached to the upper opening 3C of the appliance body 1, and three stove parts 5 each having a heat source 4 such as a halogen lamp are provided inside the appliance body 1, as shown in FIG. 1(a). A residual heat display section 6 provided near the stove section 5 is arranged in the following order from below: a light emitting section 7 such as a mini lamp, the other glass plate 8 with a groove with a mark reminding people not to touch it, and the heat-resistant glass 2. The light emitting section 7 and the other glass plate 8 are arranged in a lamp house 9.

Three residual heat display sections 6 are provided corresponding to the number of stove sections 5, and the other glass plate 8 has a mark of a hand plus an "X" as shown in FIG. The display size 10 is also enlarged.

As described above, the residual heat display sections 6 are provided near the stove sections 5 in accordance with the number of stove sections 5, and the residual heat display is simply performed through the heat-resistant glass 2 in the small diameter display zone 10. L.E.
The light emitting part 7 of the D lamp etc. emits red light (Fig. 4(b))
, (C)), a residual heat display form is provided in which a large display zone 10 and a mark to call attention to the other glass plate 8 are added to the display zone IO.

In the above configuration, when the heat a4 of the halogen lamp etc. installed in the stove section 5 is not energized, that is, when the temperature of the stove section 5 is low, the residual heat is displayed as shown in Fig. 3(a). The light emitting part 7 of the part 6 is off, while the mark on the glass plate 8 is not visible. On the other hand, the stove part 5
By energizing a heat source 4 such as a halogen lamp disposed inside and applying a predetermined applied voltage, the halogen lamp or the like reaches a predetermined temperature, and heat is transferred to a heated object (not shown) via the heat-resistant glass 2. Ru. Thereafter, when the cooking heating is finished and the power to the heat [4 of the stove part 5 is turned off, the stove part 5 is in a high temperature state. This temperature is detected by a temperature sensor (not shown) provided in the stove section 5, and the light emitting section 7, such as a mini lamp, provided in the residual heat display section 6 is energized, as shown in Fig. 3 (+). On the other hand, the mark on the glass plate 8 will be clearly indicated by flashing in red in a rapid cycle. When the temperature decreases due to natural cooling and becomes below a predetermined temperature (temperature that will not cause burns even if touched), the temperature sensor (not shown) detects this, and a light emitting device such as a mini lamp provided in the residual heat display section 6 detects the temperature. 7 is off. The display will be (al) in Figure 3.

Next, when you have finished cooking on one of the multiple stoves and there is residual heat and the warning mark on the display section 6 is blinking in a slow cycle with the light emitting section 7 on and off, the other stove is turned on. When cooking on a stove, the display zone is large and the warning mark is red and flashing in small steps, which is a nuisance, so while the stove is energized, the flashing cycle is It is made more relaxed. In other words, the on/off cycle of the light emitting part is controlled to be fast or slow depending on whether the stove part is energized or de-energized. Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) If the temperature of the heat-resistant glass is high due to the high temperature of the stove, there is a large mark to remind you not to touch it, and it is clearly indicated by flashing in the display zone in red. You can tell at a glance whether you are using the service or not. This eliminates the possibility of accidentally touching the heat-resistant glass because it is difficult to see, which directly leads to the prevention of burns.

(2) A residual heat display is provided for each stove. Therefore, it can be determined at a glance which part of the heat-resistant glass has a high temperature due to which part of the stove has a high temperature.

This greatly reduces the chance of accidentally touching the heat-resistant glass and prevents burns.

(3) During cooking, it can be a nuisance if the display zone flashes in a slow cycle, so we use a control method that flashes the display zone in a slow cycle only at this time, so you don't have to worry about it. You can cook without it.
